Yin-Yang regulation of adiponectin signaling by APPL isoforms in muscle cells.
APPL1 is a newly identified adiponectin receptor-binding protein that positively mediates adiponectin signaling in cells. Here we report that APPL2, an isoform of APPL1 that forms a dimer with APPL1, can interacts with both AdipoR1 and AdipoR2 and acts as a negative regulator of adiponectin signaling in muscle cells. Overexpression of APPL2 inhibits the interaction between APPL1 and AdipoR1, le...
متن کاملin vitro Anti-Proliferative Effect of Adiponectin on Human Endometriotic Stromal Cells through AdipoR1 and AdipoR2 Gene Receptor Expression
Background: Endometriosis is a complex disorder in reproductive age women which consist of stromal and epithelial cells implantation outside the uterine cavity. Adiponectin is a member of cytokine family with various metabolic roles and proliferation inhibition of many cancer cells. The aim of the present research was to determine adiponectin effect on human endometriotic stromal cells (ESCs) p...
متن کاملRole of adiponectin receptors, AdipoR1 and AdipoR2, in the steroidogenesis of the human granulosa tumor cell line, KGN.
BACKGROUND Adiponectin is involved in the regulation of energy homeostasis and more recently in the reproductive functions. We have previously shown that adiponectin receptors (AdipoR1 and AdipoR2) are expressed in human granulosa cells. However, it remains to be investigated whether both AdipoR1 and AdipoR2 or only one of these receptors serve as the major receptor(s) for adiponectin in human ...
متن کاملAPPL1: role in adiponectin signaling and beyond.
Adiponectin, an adipokine secreted by the white adipose tissue, plays an important role in regulating glucose and lipid metabolism and controlling energy homeostasis in insulin-sensitive tissues. A decrease in the circulating level of adiponectin has been linked to insulin resistance, type 2 diabetes, atherosclerosis, and metabolic syndrome. Adiponectin exerts its effects through two membrane r...
متن کاملAdiponectin-induced eNOS activation and Nitric Oxide Production are Mediated by APPL1 in Endothelial Cells
Adiponectin protects the vascular system partly through stimulation of endothelial nitric oxide (NO) production and endothelium-dependent vasodilation. The present study investigated the role of the two recently identified adiponectin receptors (AdipoR1 and AdipoR2) and their downstream effectors in mediating the endothelium actions of adiponectin. In human umbilical vein endothelial cells (HUV...
